Abstract

The invention discloses a production process of electroconductive glass fiber. The technical scheme is realized in such a way: the electroconductive glass fiber is composed of the components in percentage by weight: 95-70% of matrix glass and 5-30% of nano-silver. The production process of the electroconductive glass fiber comprises the steps of melting raw materials for producing the matrix glass; drawing to form a glass fiber filament; immersing the glass fiber filament to a nano-silver colloid solution for 15-20S, and airing by using hot air with the temperature of 70 DEG C after the surface of the glass fiber is sufficiently coated by a nano-silver colloid to initially prepare the electroconductive glass fiber; and placing the electroconductive glass fiber into deionized water to soak for 40-60S, and drying to obtain a finished product of the glass fiber with strong conductivity. The production process has the following beneficial effects that the production cost in the embodiment is relatively low, and the nano-silver colloid is simple in preparation and easy to operate; and the conductivity of silver is best in all metals, so that the glass fiber can take effects in more fields.

Description

technical field [0001] The invention relates to the technical field of conductive materials, in particular to a production process of conductive glass fibers. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. It has good insulation, heat resistance and corrosion resistance, and high mechanical strength. It is often used as a reinforcing material in composite materials, heat insulation materials and circuit substrate materials. It is widely used It is used in many fields of national economy such as construction, transportation, electronics, electrical, chemical industry, metallurgy, environmental protection, national defense, etc. Glass fiber is brittle, has poor wear resistance and electrical conductivity, which reduces the cost performance of glass fiber to a certain extent and limits its application range. Conductive glass fibers can be prepared by electroless metal plating on glass fibers. [0003] Patent applica...
